Description

Technical Field

[0001] This utility model relates to the field of cell culture plate technology, and in particular to a multi-specification cell culture plate. Background Technology

[0002] Cell culture plates are biological tools. Different shapes of culture plates have different uses. For cell culture, flat-bottomed plates are usually chosen because they facilitate microscopic observation, have a clear bottom area, and ensure a relatively consistent cell culture medium level. Therefore, when performing experiments such as the MTT assay, flat-bottomed plates are generally used for both adherent and suspension cells. Flat-bottomed culture plates must be used to measure absorbance values.

[0003] The existing technical solutions mentioned above have the following drawbacks: most existing cell culture plates only have culture wells with a single diameter, but the single diameter culture wells can cause contamination when transferring cells between different plates, reducing the overall culture effect.

[0010] Furthermore, the culture frame has an open lower end face, and the insertion groove and through groove inside the culture frame are respectively distributed corresponding to the first culture plate, the second culture plate and the third culture plate.

[0011] By adopting the above technical solution, the culture frame with an open lower end can ensure the rapid assembly and positioning of the first, second, and third culture plates, which can effectively reduce contamination when transferring cells between different plates.

[0012] Furthermore, a fixing screw is threadedly connected to the side of the culture frame away from the first culture plate, the second culture plate, and the third culture plate. Fixing screw holes are opened on the side of the first culture plate, the second culture plate, and the third culture plate near the fixing screw. The fixing screw passes through the culture frame and is threadedly connected to the fixing screw hole.

[0013] By adopting the above technical solution, the first culture plate, the second culture plate, and the third culture plate are easy to install and disassemble, increasing the overall flexibility, while ensuring that different plates can be easily replaced according to the actual situation.

[0014] Furthermore, the culture frame has a positioning screw hole and a nut groove on the side near the fixing screw. The nut groove is located outside the positioning screw hole, and the threaded end of the fixing screw passes through the positioning screw hole and is threadedly connected to the fixing screw hole.

[0015] By adopting the above technical solution, the nut groove can place the nut of the fixing screw, so as to facilitate the installation and disassembly of the first culture plate, the second culture plate and the third culture plate, without affecting the normal use of the whole.

[0016] Furthermore, the apertures of the first culture tank, the second culture tank, and the third culture tank are different.

[0017] By adopting the above technical solution, a first culture tank, a second culture tank, and a third culture tank with different pore sizes are integrated into one unit for the gradual expansion of cells.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. It adopts a first culture tank, a second culture tank and a third culture tank with different pore sizes. The three specifications of pore sizes are integrated into one, which is used for the gradual expansion of cells.
